yes for a while we did before emptying the system before replacing a radiator and forgetting to put some back in. Does it really make a difference? We have a combi boiler with a built on 40 litre tank - Viessmann. So yes a pressure gauge

I have 14 radiators, most of them installed between 12 and 20 years ago. One old one from the 1970s. I keep getting sludge build up blocking my Viessman boiler heat exchanger and done a powerflush 2 years ago and the water is getting murky again. Cleaned out the Magnaclean a couple of times...

"It MUST be removed from the system with several" I didnt understand this statement...several what?

Thanks for the reply. 14 radiators most are within 10-15 years old and one is 40 years probably. What brand of cleaner do you recommend? Which is the harsher and softer one?

Also how do these so call cleaners work, do they help dissolve the hardened particles which block the heat exchanger?

I know there are several products on the market to pour into my Magnaclean, ranging from Ferrox F3 and F8, Adey MC3 cleaner, Sentinel X800 etc I had my system power flushed two years ago but the problem has reappeared and was advised by a few different engineers that the system should be...

sorry I think I’m getting my words mixed up. The button is fully out not stuck in. I bought they key just in case it wasn’t fully out thinking it might come out more, but no. The damn alarm control panel will just not set when I either type the code or use the tag key. Any ideas what I...

Hi I obtained a key but unfortunately it did not help because it appears the red button is sufficient depressed that it was not stuck inside. Any other suggestions on how I can rid the rid light on the panel and reset this because the darn thing will not set the alarm whilst it says that the...

Got quoted for an alarm for my commercial shop recently, is the Castle Euro 46L EOL 8 to 46 alarm alarm any good? I wanted the ability to get remote notifications via an app etc.

Thanks. Is there definitely only the one type of key, I mean, its not likely I will get the wrong one if I order the one in your image?

One of employees accidentally triggered the panic alarm by pressing against the red push button at our shop reception desk. The button is not fully depressed so I think the chair arm must have knocked it. In any case I tapped the security tab on the panel to stop the sounder. But the panel...

Thanks. Spoodie, When you say switch, you mean even one of those TP devices costing circa £25 that has another 4 or 5 ports or one of those larger Cisco arrays that go on the cupboard?

Also what is the best all round WiFi extender for the office to use to connect to my BT fibre WiFi? Better to go with mesh or just standard extender?

Hi I have a fibre line into my office which then feed a network switch which then routes to about 50 other network ports around my building. If one of the rooms had a 3 port wall mounted switch built onto the wall and that is proving insufficient for my needs, can one of those Ethernet...

Hi Pls see door closer on attached pic. It’s for my office door. How can I stop it from slamming shut, is there something I can adjust for a softer close?

If we’re leasing the building for 15 years. I doubt we need permission to install fibre broadband cables. I understand contention ratios are higher on residential compared with business broadband.

I’m just wondering if there is something in the legal contract which might limit is used to residential.

Does anyone know whether it is not permitted to sign up for residential fibre broadband to be used in a commercial premises?

Yes this is/was in the pipeline, just work going on at the property.

Had to call upon my home emergency insurance policy and it transpires that literally only two screws were used. Have now put like 5 screws on the bottom and a few on the side. I doubt the other windows are any better which means the risk remains of them returning and trying another window...
